In situ coordinated HTL strategy for high-performance and scalable perovskite solar cells.

ABSTRACT: Achieving uniform and stable hole transport layers (HTL) is crucial for large-area perovskite solar cells (PSCs). However, current self-assembled monolayer (SAM)-based HTL suffer from weak interfacial adhesion, poor film uniformity, and limited stability, constraining their scalability. Our study proposes an integrated HTL strategy with in situ SAM anchoring during NiO_x synthesis, forming a type of scalable, high-performance, and durable HTL. This strategy significantly enhances molecular ordering, energy level alignment, and charge extraction, leading to a more pronounced performance improvement in large-area slot-die coating modules. PSCs with this HTL achieved a champion PCE of 26.02% (with an active area of 0.0655 cm²), while large-area modules reached 22.80% at 2
